摘要:
为清楚了解磁流体热疗设备产生的电磁场的分布,本文采用有限元方法对自制的设备原型建立三维模型并进行了优化,计算了该模型在静态和谐态下产生的电磁场的分布,对磁极中间的气隙宽度在20~40 mm范围内变化时的磁场强度进行了对比.选取气隙宽度为30 mm时计算电磁场的磁场强度、电感和涡流损耗,所得结果与实验测量值完全吻合,验证了模拟计算的可靠性.
Abstract:
In order to improve therapeutic effects, the distribution of electromagnetic fields arisen by the magnetic fluid hyperthermia(MFH)treatment system need be investigated more explicitly. Three-dimensional finite element method(FEM)models for the prototype of the MFH treatment system designed by us were constructed and optimized. The distribution in static and harmonic magnetic fields were calculated and the magnetic intensities were compared when the spans of atmosphere between magnetic poles were 20 to 40 mm. Then magnetic intensity, induction and eddy current loss were also computed when the span was 30 mm. The results agree with the experimental measurements, which proves the effectiveness and feasibility of this method.
